TMS3728ASSIGNMENT 3 2024
To complete this assignment, please work through learning units 4, 5 and 6
of your study guide.
Question 1
1.1. Consider the topic of cell, the basic unit of life in Grade 9, and explain how you
would use the 5Es instructional model to teach it to promote learners’
engagement.
To teach the topic of "cell, the basic unit of life" to Grade 9 students using the 5Es
instructional model:
Engage
Capture students' interest and assess their prior knowledge.
Start with a thought-provoking question: "What do you think makes up every living
thing around us?" Show a short video or an animation about the diversity of life, ending
with a magnified view of cells.
Prompt students to share what they know about cells. Ask questions such as "Have
you heard the term 'cell' before?" and "What do you think a cell looks like?"
Explore
Objective: Allow learners to investigate and discover information about cells.
Provide microscopes and prepared slides of different types of cells (e.g., plant cells,
animal cells). Have learners observe and record their findings.
Learners work in small groups to compare their observations. Encourage them to note
the similarities and differences between the cells they observe.
Questioning: Ask guiding questions like "What shapes do you see?" and "Can you
identify any structures within the cells?"
Explain
Help learners construct a deeper understanding based on their explorations.
Activity
,Conduct a class discussion where groups share their observations. Use a diagram of
a cell projected on the board to identify and label key structures (nucleus, cytoplasm,
cell membrane, etc.).
Provide a clear explanation of cell theory, the functions of different cell parts, and the
differences between plant and animal cells. Relate this information back to the
learners' observations.
Elaborate
Extend learners' understanding and apply it to new situations.
Assign a project where learners create 3D models of plant and animal cells using
various materials. They should include all major organelles and provide a brief
description of each function.
Discuss how understanding cells is crucial in fields like medicine, genetics, and
environmental science. Invite learners to consider how cell biology impacts their daily
lives (e.g., understanding diseases, growth, and nutrition).
Evaluate
Objective: Assess students' understanding and provide opportunities for self-
assessment.
Activity: Have learners present their 3D models to the class and explain the function
of each part. Use a rubric to assess their understanding and creativity.
Quiz
Administer a short quiz covering key concepts about cells. Include multiple-choice
questions, short answers, and labeling diagrams.
Ask learners to write a reflection on what they have learned about cells, how their
understanding has changed, and any questions they still have. Encourage them to
think about how they can apply this knowledge in future studies.
, 1.2. Read learning unit 4 of the study guide and briefly reflect on how you can use
your explanatory skills as a teacher to provide good explanations in any Natural
Science topic in the Senior Phase. Make the choice of your topic explicitly clear.
Topic: Photosynthesis
As a teacher, using explanatory skills effectively is crucial for making complex scientific
concepts like photosynthesis accessible and engaging for Senior Phase students.
1. Prepare the Mind for Learning
Objective: Set the stage for understanding photosynthesis.
Begin with an engaging question to spark curiosity: "Have you ever wondered how
plants make their own food?" Show a time-lapse video of a plant growing, highlighting
the importance of sunlight.
Context: Explain why photosynthesis is vital not only for plants but for all life on Earth,
as it produces oxygen and forms the basis of the food chain.
2. Break Down Complex Information
Objective: Simplify and clarify the process of photosynthesis.
Use a clear and concise explanation of photosynthesis, highlighting the role of
chlorophyll, sunlight, carbon dioxide, and water. Introduce the chemical equation for
photosynthesis:
6𝐶𝑂2+6𝐻2𝑂+𝑙𝑖𝑔ℎ𝑡𝑒𝑛𝑒𝑟𝑔𝑦→𝐶6𝐻12𝑂6+6𝑂26CO2+6H2O+LIGHTENERGY→C6H12O6+6O2.
3. Use Practical Activities
Objective: Provide concrete experiences to reinforce abstract concepts.
Activity: Conduct a simple experiment where students observe the production of
oxygen by aquatic plants (like Elodea) under different light conditions. Have them
measure the rate of bubble formation as an indicator of photosynthesis.
